fix(borders): always validate border client area

Browse Source 
This commit pushes up the calls to BeginPaint and EndPaint in the border
callback function to ensure that the client area of the border rect is
always validated after calls to InvalidateRect from the update fn.

The callback now also logs errors whenever it is not possible to get the
border rect to operate on for any reason.

There was a call at the end of this logic to ValidateRect which has been
removed as the validation is already handled by the call to BeginPaint.
